Configuring the QLogic HBA for a host that runs the Microsoft Hyper-V operating system
After you install the QLogic host bus adapter (HBA) and the device driver on hosts that are running the Microsoft Hyper-V operating system, you must configure the HBA.
About this task
To configure
the HBA BIOS, either use the QLogic HBA
manager software or reboot into the Fast!UTIL tool. Configure the
following settings:
- Host Adapter BIOS: Disabled (unless the machine is configured for SAN Boot)
- Adapter Hard Loop ID: Disabled
- Connection Options: 1 - point to point only
- LUNs Per Target: 0
- Port Down Retry Count: 15
Set the execution throttle to a suitable queue depth for your environment. A suggested value is 100. If you are using subsystem device driver (SDD) 1.6 or higher, set Enable Target Reset to No. See Table 1 to include the required parameters for the registry key.
Key | Required parameters |
---|---|
HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Services > ql2xxx > Parameters > Device > DriverParameters | Buschange=0;FixupInquiry=1 Note: If
you are using QLogic driver version 9.1.2.11 or higher, Buschange cannot
be set to zero. See your device driver documentation for details.
